ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 765,071, dated July 12, 1904.

Application filed July 27, 1903. Serial No. 167,067. (No model.)

To all whmn it mag concern.-

Be it known that we, JOHN HENRY EICI-ILER, a citizen of the United States, and JULIUS BECKER, a subject of the Emperor of Germany,

large degree the element of danger in the use of machines or apparatus of this character and to render them more or nearly automatic or self-regulating in their operation.

In our present'machine the production of gas is governed by the consumption, and the quantity generated always bears a certain proportion to the quantity drawn off for immediate consumptiomso that no considerable quantity of gas is allowed to accumulate in the apparatus and no gasometer or storagechamber is used. The quantity of the gas producing substance fed or introduced to the generatingchamber is v governed and regulated by novel mechanism controlled directly by the variations taking place in the body of generated gas in the compartment from which the gas is carried away to the burners, the calcium carbid fed to the generating-chamber being increased or reduced automatically through the variations in the consumption of gas, and the supply of the gas-producing substance being cut 05 Whenever the quantity of gas generated exceeds the quantity being consumed and as often as the gas begins to accumulate in the compartment fromwhich it is drawn for use.

To such end and object chiefly our invention consists in certain :n'ovel parts and combination of parts, as hereinafter described, and

pointed out in the claims at the end of this specification, the accompanying drawings, forming part thereof, being referred to by figures and'letters.

of a machine or apparatus embodying the novel features of our invention. Fig. 2 is an inverted plan of the float that controls the feedregulating valve of the calcium-carbid chamber. Fig. 3 is a view of the stationary body or shell, and Fig. 4: a view of the receptacle for the calcium carbid.

The body A of the machine being made, preferably, of cylindrical form is divided by a horizontal partition 6 into an upper compartment d and a lower compartment 6, the lower one constituting a gas-holding chamber and the upper one serving for a reservoir or receptacle from which the lower compartment is supplied with water. A tube f on the outside connects the aperture 9 in the side of the water-reservoir with. an aperture 72 situated in the side of the gas-holding compartment, the latter aperture being always covered by the water to prevent the escape of gas into the upper compartment. An opening to in the centerof thefloor of the upper compartment is surrounded by a cylindrical extension at of the same dimensions diametrically as the opening and of proper length to extend below the level of the water, is closed at the lower end, and always sealed by the Water standing in the lower compartment. These parts form the shell or body of the apparatus, to which the usual pipe 19 is coupled for carrying away the generated gas for use, and an outlet in is provided for drawing ofl? the Water when it is desired to clear the compartment.

The receptacle for the calcium carbid is a separate vessel fitting in the top of thewaterreservoir (Z, from which it is readily lifted for clearing out or recharging, and consisting of the receptacle 8 of conical shape, with an outlet-aperture t in the end of its funnelshaped bottom, and a tubular conductor w, extending downward from the outlet. This tube or cylindrical portion of the carbidholder fits inside the cylindrical casing that extends downward from the horizontal partition 6 into the generating-chamber, and the lower end of the tube makes a close joint with a cup-shaped flange 1 on the end of the easing when/the holder rests on the top rim of the body A. An opening in the top of the holder closed by a screw-cap m is provided for introducing the carbid, and a valve 2 inside controls the outlet-aperture through which the particles are discharged into the tube. The valve is of cylindrical shape, with conical ends, and is connected with a float 4 in the generating-chamber by a spindle 3 and 'a hanger or bracket formed of angularly-bent rods 5, attached to the float. Being connected with the float in this manner, the valve responds to the movements of the float asthe latter rises and falls under the variations in the water-level, and by its movements up and down in the contracted lower part of the"calcium-carbid holder, as well as by virtue of its form, the valve reduces or increases the area of the outlet and also I keeps the particles in motion sufiiciently to prevent them from packing or choking in the lower end of the j The float is best formed of a holreceptacle. low air-tight rlng surrounding the statlonary casing. The valve-spindle extending down through the tubular extension of the calcium-- rises under a reduction in the gaseous pressure. As the pressure increases in the space above the water into which the gas rises as fast as it is generated in the bottom of the chamber, the water displaced by the pressure rises in the reservoir above through the connecting-passage, and as the pressure is again reduced the displaced water flows back into the generating-chamber, raising the waterlevel therein and the float with it. The changes of the pressure taking place in the gas-holding space, due to variations in the consumption of the gas, thus act directly on the valve and-control the How of the calcium carbid accordingly. Vvhenv the gas is generated faster than it is drawn ofl? for use and the quantity accumulating reaches the desired limit, the float drops sufliciently to bring the valve to a seat and cut 03 the supply of the material. This action of the valve can be regulated by varying the length of the spindle 3, connecting the valve with the float. Additional security against accumulationof the gas in excessive quantities in the generating-chamber is provided by carryingan escapepipe 8 from an aperture in the side-of the chamber to the atmosphere outside. This escape-outlet, being situated below the working level of the body in the chamber, is sealed under ordinary conditions, but is uncovered whenever the water-level is depressed by the confined gas to a point where it will uncover the outlet.

From the foregoing it will be seen that the production of gas in our apparatus is limited and controlledv by the consumption of the gas, that the calcium carbid is fed to the generating-chamber in varying quantities which are regulated automatically by the consumption of the gas, and that the communication between the calcium-carbid receptacle and the generating-chamber is cut off whenever the gas is generated faster than it is carried ofi" for use, and a greater quantity is accumulated in the chamber than is required to secure a steady flow to the burners. The construction also dispenses with connecting-pipes between the calcium-carbid holder and the generatingchamber and gas holding space, thereby avoiding joints and couplings that are liable to break.

Having thus fully described our invention, what we claim as new therein, and desire to secure by Letters Patent, is

1. In an acetylene-gas generator, a generating-chamber containing a water seal, a water-reservoir above the Said chamber separated therefrom by a horizontal partition, a pipe connecting the generating-chamber with the water-reservoir, said partition having an aperture and a' tubular casing extending downward from the aperture into the generating-chamber; in combination with a carbid vessel comprising a receptacle having sloping Walls and an outlet-aperture in the bottom, and atube extending downwardly from the outlet through the horizontal partition and into. the casing beneath, a valve controlling the outlet, and a float in the generating chamber connected with the valve,

2. In an acetylene-gas generator, the combination of a generating-chamber containing a water seal, a water-reservoir situated above said chamber, a water-duct leading from the lower part of the water-reservoir into the generating-chamber below the working level of the water therein, a carbid-receptacle havbottom and a tubular extension therefrom fitnames in the presence of two subscribing Wittlng into the casmg of the generatmg-chamnesses.
